AbstractThe 2003-04 Winter rehabilitation of Regina?s Wascana Lake (the ?Big Dig?) was intended to improve water quality in the lake. It presented a unique opportunity to monitor the quality of lake water from ?day one? by tracking changes in various physical, chemical and biological parameters over the course of the lake's maturity. An existing assessment tool, the CCME Water Quality Index (WQI) was used to evaluate data from water samples taken at several sites within the lake during the first two years. The WQI includes measures of how many parameters exceed national water quality guidelines, how often, and by how much. Data for the first two years show that the lake remains a poor site for recreational activities involving extensive contact with the water (WQI = 32) due to high levels of bacteria (Total coliforms, E. coli, fecal Streptococci) and pH. A significant waterfowl population resides in and around the lake, contributing to the high counts of fecal bacteria. Bacterial counts increased as the lake warmed throughout summer. Wascana Lake provides a marginal environment for wildlife based on the parameters examined (WQI = 57). Phosphorus and nitrogen levels are elevated to levels that may contribute to overgrowth of vegetation and algae.
